M4 rail conversion to m16 rails

Hey I have a M4 I've turned into a DMR and I still have standard M4 rails on it with a 509-520mm long outer barrel, now if you didn't get that it means I have like 12in of barrel past my rails and it looks ridiculous.

Now I have looked for m16 rails an stuff, but I want to know your suggestions for converting my rails to full length m16

(Which I've seen are 20in long) and I also want to know if I will need a new barrel or etc...

Look into some 12 inch free float rails. They should look really good.

I have a CQB model so I already have those but I'm looking for some 20 inch ones so that there isn't a lot of my barrel showing and it looks more like a sniper than an M4 with a freakin huge barrel haha
